My bio teacher was looking up pornographic materials.
That's called research LOL, no one else has stated an opinion whether school kids should be 'helped' to bypass systems put there for good reason - online messengers for example where people can prey on kids at school - 'yeh see you after school for a burger, from kid 15' (actually 50 year old perv about to kidnap other kid) still wonder why schools don't like messenger services especially through their systems.
